The projectile is provided at its front end 2 zwith acavity, where-v in a fulminant 3 with primer 4; is inserted: In theembodiment 'ofthe'projecti'le shown I on the drawing a safety body 5 ofa slow burning composition is provided in front of 0 said primer andfulminant in order to avoid unintentional ignition f by contact. Thesafety body can be used as a retarder of the explosion of theprojectile. The numeral 6 I designates a cylindrical cavity at thefro-ntend of the projectile which is adaptedto ceivin'g a 'sliding gate in'iiig gate cranked level-"13.

5. A projectile holding or suspension device comprising a reciprocatingholding member for projectile proper, a guideway and holder fora fusemember for the projectile arranged substantially parallel to thedirection of movement of the reciprocating member, a fuse actuatingmember adapted to displace a fuse within said guideway, a slide gatearranged transversely to said guideway, the fuseactuating member and theslide gate both in operative connection with the reciprocatingprojectile holding member and so coordinated to each other that theslide gateis withdrawn from the area of the guideway when the fuseactuatingmember advances towards the gate.
